Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve a sequence of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A series of A-range actuators had reached the tip of their operational life after long service in a challenging setting. BAE Systems wanted to retain all the advantages of electric actuators, so IQ3 actuators were chosen. Dollar had to be specifically tailored by Rotork to beat issues round confined spaces and tough access.
IQ3 actuators and IS gearboxes had been mechanically adapted in order that both actuator and gearbox might be operated by hand with out coming into the confined space. Rotork designed particular hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the necessity for confined house access.
Actuators within the IQ vary are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. They have a sophisticated twin stacked show with configurable knowledge logger functionality, and an absolute position sensor offers reliability and accuracy.
